NECK YOKE.

Application filed February 2, 1925.

To all whom it may concern:

Be I it known that we, ALBERT E. Sol-morn, EDWARD SCHRUTH, and JOHN Sonnu'rrr, citizens of the United States of America, and residents of Pepin, in the county of Pepin and State of Wisronsin, have invented certain new and useful ful Improvements in Neck Yokes, of which the following is a specification.

This invention relates to neck-yokes, and has for an object the provision of a novel coupling between the neck-yoke and the tongue of a wagon whereby the strength of the neck-yoke is increased, rather than diminished, in attaching the coupling to the neck-yoke.

It is a further object of this invention to produce a mounting for the tongue or pole ring which provides for the elimination of strain on the central portion of the yoke, and the said invention comprises parts which are readily assembled and secured on a neckyoke in order that they can be expeditiously disassembled for the substitution of broken or otherwise impaired parts.

lVith the foregoing and other objects in view, the invention consists in the details of construction, and in the arrangement and combination of parts to be hereinafter more fully set forth and claimed.

In describing the invention in detail, reference will be had to the accompanying drawings forming part of this application wherein like characters denote correspond.

ing parts in the several views, and in which- Figure 1 illustrates a plan view of a neckyoke with a device embodying the invention applied thereto;

Figure 2 illustrates an enlarged detail view of a fragment of the neck-yoke with parts of the device in section;

Figure 3 illustrates a sectional view on the line 3-3 of Fig. 2; and

Figure 4 illustrates a sectional view of the neck-yoke and attachment on the line 4.-t of Fig. 2.

In these drawings, 5 denotes a neck-yoke having an enlarged central portion 6 with shoulders 7 and 8 at the ends of the enlarged portion, the said shoulders being preferably beveled. It is desirable to make the neck-yoke of wood, and it is supplied with appropriate fittings at its ends for attachment to a harness.

Serial No. 6,359.

A ferrule-like body is applied to the neck-yoke at each end of the enlarged portion, and they are usually duplicates, one of the other, so that a description of one will sutlice for an understanding of their construction by one skilled in the art. Each member is in the general form of a ring 1) whose inner edge 10 is preferably beveled to conform to the configuration of the shoulder which it contacts, and each member has an inwardly projecting body or lug 11 with a concave face conforming to the external surface of the enlarged central portion of the yoke, and each member has a slot 12 forming a seat for a ring or link 13 andan anti-friction roller 14, the said ring hearing on the roller, as will presently appear, when the device is in operation.

Each member has an aperture 15 which extends substantially at right angles to the longitudinal axis of the recess or slot 12, although the said aperture as here shown is slightly curved and the aperture of one member registers or aligns with the aperture of the other member in order that a bolt 16 may be inserted in the apertures of the members for the purpose of drawing the said members toward each other with their rings firmly seated on the shoulders of the enlarged portion of the yoke. The bolt 16 has a threaded end 17 engaged by a nut 18 so that by turning the nut, the tension or pull is exerted by the bolt for drawing the members toward each other and in engagement with the shoulders, as heretofore described.

The tongue or pole ring 19 is applied to the links or rings 13, and it follows from an inspection of the drawing and from the foregoing description that should either of the rings or links 13 or the ring 19, or the rollers for the rings or links 13 become impaired, the assembly may be disconnected or disassociated for the purpose of renewing worn or broken parts As the members which are applied to the neck-yoke may be constructed as steel castings or malleable castings, the cost will be comparatively small, whereas their use avoids the weakening of the neck-yoke through the use of holes for anchoring the pole ring thereto; and furthermore, owing to the fact that the members are connected to the neck-yoke at locations somewhat remote from the center, the strain on the neclc yoke is distributed to a greater degree than it is in those devices now commonly used.

:We claim: a

1. A neck-yoke having an enlarged portion at its center with shoulders at the ends of said enlarged portion, members having rings applied to said neck-yoke, the said members and rings being shaped to the configuration of the'should'ers and the surface of the said enlarged portion, means for drawing the members toward each other with the rings in engagement with the shoulders, and a pole ring connected to said members;

2. A neck-yoke having an enlarged portion at its center with shoulders at the ends of said enlarged portion, members having rings applied to said neck-yoke, the said members and rings being shaped to the configuration of the shoulders and the surface of the said enlarged portion, means for drawing the members toward each other with the rings in engagement with the shoulders, a pole ring, and means for connecting the pole ring to said members.

3. A neck-yoke having an enlarged central portion with shoulders at its ends, members fitted on the said yoke and bearing against said shoulders, the said members having apertures, and also having seats intersected by said apertures, rings in the seats, anti-friction rollers Within the rings, said anti-friction rollers having apertures, and a bolt extending through the apertures of the members and the apertures of the anti-friction rollers for assembling the rings with relation to the members, the said bolt being operative to draw the members in contact with the shoulders of the yoke.
